This invention relates to compounds having the formula: ##STR1## in which R.sub.1 and R.sub.2 are independently hydrogen, a C.sub.1-4 alkyl group or an aliphatic or aromatic acyl group, provided R.sub.1 and R.sub.2 are not simultaneously hydrogen, or, together with the nitrogen atom to which they are attached, R.sub.1 and R.sub.2 form a 5- or 6-membered ring which may carry another heteroatom; R.sub.3 is a C.sub.1-4 alkyl group; and R.sub.4 and R.sub.5 represent independently a hydrogen or halogen atom, a C.sub.1-4 alkyl group or a C.sub.1-4 alkoxy group; and the acid addition salts of the above compounds. Said new compounds have an anxiolytic and diuretic action, together with a spasmolytic action of non-.alpha.-adrenalytic nature on the unstriated muscle fibers.
这项发明涉及具有以下结构的化合物:##STR1## 其中R.sub.1和R.sub.2独立地是氢、C.sub.1-4烷基基团或脂肪族或芳香族酰基,前提是R.sub.1和R.sub.2不能同时为氢,或者与它们连接的氮原子一起,R.sub.1和R.sub.2形成一个可能携带另一个杂原子的5-或6-成员环;R.sub.3是C.sub.1-4烷基基团;R.sub.4和R.sub.5独立地代表氢或卤素原子、C.sub.1-4烷基基团或C.sub.1-4烷氧基团;以及上述化合物的酸盐。这些新化合物具有抗焦虑和利尿作用,以及对非α-肾上腺素能性质的平滑肌纤维的解痉作用。
